  • Metallurgy II: Annealing, Normalizing, and Tempering

    Tempering: Once hardened, steel will often be too hard and brittle to be effectively worked. Therefore, the strains must be relieved in order to provide a proper balance between hardness and ductility. This process is called tempering. It is called tempering because the process tempers the effects of a hardening treatment.
